Watery Enceladus
www.physicstoday.org F inding liquid water is a fundamental quest of planetary science. Because H2O is the simplest stable compound of the first and third most cosmically abundant elements, it is one of the commonest molecules in the universe. Our solar system is no exception: During its formation, temperatures in the protosolar nebula were low enough that water ice could condense in most place...
متن کاملEnceladus' water vapor plume.
The Cassini spacecraft flew close to Saturn's small moon Enceladus three times in 2005. Cassini's UltraViolet Imaging Spectrograph observed stellar occultations on two flybys and confirmed the existence, composition, and regionally confined nature of a water vapor plume in the south polar region of Enceladus. This plume provides an adequate amount of water to resupply losses from Saturn's E rin...
متن کاملMethanol on Enceladus
[1] Near infrared spectra of the surface of Enceladus returned by Cassini show the presence of an absorption feature at 3.53 mm, ascribed by Brown et al. (2006) to ‘‘short chain organics,’’ and by Newman et al. (2007) to hydrogen peroxide. We assign this feature tentatively to methanol. Variations in the peak position of the feature suggest that methanol in the ‘‘tiger stripes’’ region may be s...
متن کاملGeodetic Games
We show that the geodetic game, introduced by Fraenkel and Harary, is decidable in polynomial time on AT-free graphs.
متن کاملTidal heating in Enceladus
The heating in Enceladus in an equilibrium resonant configuration with other saturnian satellites can be estimated independently of the physical properties of Enceladus. We find that equilibrium tidal heating cannot account for the heat that is observed to be coming from Enceladus. Equilibrium heating in possible past resonances likewise cannot explain prior resurfacing events. © 2007 Elsevier ...
